yes the net force can be zero.
such force are known as balanced force.

Answer 2

Hey mate here is your answer
Yes,it is possible that force acting on a body can be zero because when you trying to push a rigid wall with your hands then you apply your maximum force but you can't push that wall in that case you have applied force but it is considered as zero because no work is done
and force is only be considered if any work is done by it other wise it will be zero
Hope you understand it mate...
